DNS resolution not working

What steps did you take and what happened:
[A clear and concise description on how to REPRODUCE the bug.]

Trying to connect to pods using Kubernetes Services results in connection refused errors.

What did you expect to happen:

Kubernetes services are working.

Anything else you would like to add:

Installed master branch version of VC on an AKS cluster.

When trying to access Service DNS, the addresses are unreachable.
Here's an example of a kubectl apply -f command that executes a registered webhook validation:

error when creating "nginx.yaml": Internal error occurred: failed calling webhook "vvalidator.kb.io": Post https://k8s-validation-webhooks-service.default.svc:443/validate-app-microsoft-com-v1alpha1-app?timeout=10s: context deadline exceeded

Containers running in a tenant namespace also cannot access DNS based services. They can, however, access Pod IPs directly.

DNS works fine in the super cluster environment.

Environment:

  • cluster-api-provider-nested version: master
  • Minikube/KIND version: AKS
  • Kubernetes version: (use kubectl version): 1.20.7
  • OS (e.g. from /etc/os-release): Ubuntu
